To all 'whom t may come/m:

Be it known that l, BRUNO LnwANDowsKI, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles o and State of California, have invented n ew and useful improvements in Air-Qushion Bumpers for Motor Vehicles, of which the following is a specication.

M invention relates to a bumper that is to particularly designed for the use upon motor vehicles. i

The principal object of my inventlon 1s to provide a strong that is of relatively simple structure, capale ble of being easily and cheaply produced and having air cushion art that will yield to a certain degree in t e event that said part strikes or contacts with a fixed or movable object.

A further object of my invention 1s to produce a bumper of neat and pleasing apearance and design, so that when properly installed it will add materiell to the appearance of the vehicle to which it 1s apae plied.

@ther objects and advantages will hereinafter appear and while l have shown and will vdescribe thev preferred form of the bumper wish it to be understood that I e do not imii myself to such preferred form, for various changes and adaptations may be made therein without departing from the spirit of my invention, as set forth in the accompanying drawings in which:

Fig. 1 is a plan view of the bumper. Fig. 2 is a side elevational view of my improved bumper in position upon the :tor-A 'ward end of the frame of the vehicle.

Fig. 3 shows in perspective the constructe tion of the bumper in acordance with. the

present invention.

Fig. l is a sectional detail illustrating the valve cap taken on the line A-A of Fi l. et i 5 is an end section taken on' the line B- of Fig. 4, showing the construction and assembling of parts relating to the invention, which is used on both ends of the bumper.

Fig. 6 is a front view of the air cushion part showing one of the various designs.

ingbodrawing which illustrates a practical em diment of my invention, 7 designates horizontally disposed arms that are secured in any suitable manner to the forward ends of the frame of the vehicle.

To the forward ends of these arms is secured a T-bar 8 by means of bolts 9. The said part 8 is extended through the entire len h of the bumper. To the part 8 an air cus ion 10 is attached by means of a steel flap 11 and screws 12 spaced at intervals 'through the entire length orD the bumper.

0n the ends the saidpscrews 12 are firmly secured to the steel washer 13, which has a slot 14 fora passage of part 11 and also has a hole 15 to receive a standard air valve i6.

To ll the air cushion with compressed air the tube 17 is used which has au air valve 16 attached to one end only. To prevent the direct contact of tube 17 with washer 13 a felt washer 18 is used.

The ends of the air cushion are secured by means of ring 19 which in turn is secured to the washer 13 by means oi screws 19, and which has a slot 20 for the location and pas sage of T-bar 8 and the dust cap :21 is se-1 cured on part 19 by means of thread Q2 which can be taken ofi' to lill the cushion with air. The cushion 10 has a various design 23 on front to suit requirements.

It will be seen from the above that the force of any blow received upon the bumper will be sustained and resisted by the eompressed air in the cushion, with the result that damage from collisions is reduced to a minimum.

A bumper of my improved construction is relatively simple and may be easily and cheaply produced vand when properly ecn.- structed, presents a neat and finished appearance.

I claiml as my invention:

1. In a bumper for automobiles, a bumper bar carried on the forward end' of the automobile, an air cushion bumper resting againstI the forward side or said bar, a ring fitting over each end of said bumper and an end oi said bar, means for securing said rings to said bumper and to said bar, and caps fitting over said rings and over the ends respectively of said bumper.

2. ln e. bumper for automobiles, u. bumper imi' eerrie on'he front' of 'the automobie,

'en air cushion bumper .resting against the fel'ward side Ofsaid bei" washers inthe ends respectively of said bumper, a! ring' tting end of-.said bumper' and ene of said washers' vtogether, screws for seeuring'eaeh ring and end of said bumper, one of 'seid washers and an end of said ball' together, and caps 'fitting 10 over Said rings :undl over the ends respectively of said bumper.
